Understanding simple stream transforms in Node.js


Understanding simple stream transforms in Node.js

To fix the issue you can do Readable streams don't on their own support transforms.
You'll want to create a stream.Transform and define its _transform(), then chain it between req and res with another .pipe():
code :
var stream = require('stream');

var server = http.createServer(function(req, res) {
  // ...

  var uppercase = new stream.Transform();
  uppercase._transform = function (data, enc, cb) {
    cb(null, data.toString().toUpperCase());  
  };

  req.pipe(uppercase).pipe(res);
})

Is there a simple way to figure out if two transforms are the same?

help you fix your problem src.pipe(dest) returns the destination stream. This pattern allows for pipe() calls to be chained:
code :
a.pipe(b).pipe(c).pipe(d)
// is equivalent to
a.pipe(b)
b.pipe(c)
c.pipe(d)
var foo = new FooModel();
var stream = foo.all();

// reply(stream.pipe(ObjectTransform));
stream.pipe(ObjectTransform);
reply(ObjectTransform);

Hope that helps Call .stream() on a native driver cursor to get a readable stream:
code :
var stream = collection.find().stream();
stream.on('data', function(doc) {
    console.log(doc);
});
stream.on('error', function(err) {
    console.log(err);
});
stream.on('end', function() {
    console.log('All done!');
});

I hope this helps you . You can't just concatenate WebM files, so you will have to either:
Build one big file by concatenating all the videos, Run them through a pipeline which concatenates the videos, or Send a list of video names and sequentially poll the videos in javascript.
